Quantum Mechanics Work to Protect Security Online
There are many indecipherable messages on the internet.
Cryptography protects bank accounts and people's identities from fraud. This allows people to feel safe about being and selling items online. However, because of the new introduction of ultra powerful quantum computers, it makes personal information easy to access and attack. Researchers have developed tiny microchip circuits which provides a level of security that is enhanced by the laws of quantum physics.
The tiny microchip circuits give out cryptographic keys using the quantum properties of entanglement, superposition, and the randomness that is provided by the quantum behavior. The system that these researchers have developed allows information to be exchanged using single photons of light in a quantum state. This being said, if someone were to try to hack someone else's transmission, they will collapse the quantum states since they are fragile and additionally end the transmission. Also, the person will be immediately alerted that their transmission was trying to be hacked. This is the first chip with a secured communication system that uses light to encode information at the single photon level, providing encryption keys with an eternal lifetime.
These researchers have continued developing this technology. The next generation of these microchip circuits will be less expensive and not have a complex manufacturing approach. They will be made out of silicon making a path for direct integration with microelectronic circuits.
